SEDENTARY BEHAVIOR IN KITCHEN IS LIABLE TO FAT ACCUMULATION AND CARDIO-METABOLIC RISK

ABSTRACTObjective: Sedentary habits are considered one of the most important reasons for various cardiovascular complication and risks. Taking into thisaccount the objective of the present study was to to explore the empirical association between accumulation of fat and heart health status among nonsedentaryand sedentary habits in kitchenof our modernized society.Method: The current study included 100 women (22-40 years old). Workers who met the inclusion criteria were assigned in to two groups: Group (I)Non-sedentary workers (n-58) and Group (II) - sedentary workers (n-42). Commonly, workers which used to do simple movement work in kitchenwere considered as control and which mostly worked at one place in kitchen for more than 6-hours of total working schedule (8–hours). were includedin sedentary workers, Anthropometric measurement like body fat ( (%waist circumference(WC), waist hip (WH) ratio, and heart rate variability(HRV)were measured and analyzed by the independent student ʻtʼ test, followed by Pearson correlation and Linear regression.Result: we observed, there was significant increase in body fat ( (%, WC, WH ratio and sympathetic dominance among sedentary participants whencompare to non-sedentary participants. There was significant negative correlation between LF and HF, body fat and HF, as well as WH ratio and HF,and significant positive correlation between body fat and LF as well as WH ratio and LF. Conclusion: These results suggest that sedentary behaviour in kitchen is associated with accumulation of adiposity and alteration of sympatho-vagalbalance, may lead to cardiometabolic risk in adult women.Key words: Body fat distribution, Heart rate variability, Sedentary habit, physical activity

Sleep restriction progress to cardiac autonomic imbalance

Previous studies have shown that night shift work is thought to be a risk factor for cardiovascular disease and inadequate sleep is a common feature of night shift work. Since it’s more difficult to maintain adequate sleep duration among night watchmen during their working schedule, hence the purpose of our present study was to investigate whether mental stress or fatigue over restricted sleep period in night shift, affects HRV, in order to elucidate on cardiac autonomic modulation among nigh watchmen. With the purpose of this, autonomic activity determined from the levels of the heart rate variability (HRV), and also measured, body mass index (BMI), body fat percentage from skin fold thickness (biceps, triceps, and sub-scapular, supra-iliac) among normal sleep watchmen) (n = 28) and restricted sleep watchmen (n = 28) at first (1st) day, fourth (4th) day and seventh (7th) day of restricted sleep period. We observed that among restricted sleep individuals, sleepiness was significant increase at 4th day and 7th day when compare to normal sleep individuals, and, there was significant increase in, mean NN, VLF, LF, LF(nu), LF/HF AND significant decrease in SDNN, RMSSD, TSP, HF, and HF(nu) at 4th and 7th day of restricted sleep period. In addition to, this variable was more significant increase on 7th day, when compare with 4th day. As well as there was significant negative correlation between LF(nu) and HF(nu) at subsequent 4th day [r (48) = −0.84; P = 0.01] and 7th day[r (48) = −0.95; P = 0.01] of restricted sleep period. However we didn’t observe any significant variation in BMI, and body fat percentage among restricted sleep individuals when compare to normal sleep individuals with in this restricted sleep periods. Hence we concluded that partial sleep loss may cause autonomic imbalance represented by increased sympathetic and decreased parasympathetic activity; as revealed by altered HRV indices observed in this study.
